1'0 ft//// w/wm if *nmy concern.-

Be it known that 1, Thomas F. ROWLAND, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented certain new and useful Improvements in OorrugatingMachines, of which the following is a specification, taken in connection with the accompanying drawings, which form a part of the same.

This invention relates to corrugating-machines, and relates especially to machines for forming undercut corrugations in sheet-metal cylinders.

In using the illustrated embodiment of this invention corrugations having arched ridges are iirst formed. These arched ridges are flattened to form substantially crenelated corrugations, and these corrugations are thereupon acted upon by a spinning mechanism to linish them and complete their undercut contour.

In the accompanying drawings, in which the same reference-numeral refers to similar parts in the several ligures, Figure 1 is a vertical sectional view of an embodiment of this invention, the machine being indicated asllattening the arched corrugations. Fig. 2 is a similar view in which the machine is indicated as forming the primary arched corrugations. Fig. 3 is a side elevation. Fig. 4 is a horizontal sectional view of the machine as shown in Fig. 1. Fig. 5 's a plan view of the same. Fig. 6 is a similar-view taken substantially on the line 6 6 of Fig. 1. Figs. 7, 8, 9, and 11 are details of the spinning mechanism, and Fig. 10 is a detail of the head.

A heavy frame is used to support the various parts 011 this machine, preferably com prising the base 1, the pillar 2, and the entablature 5, upon which the head 3 is mounted, these parts all being rigidly joined, as indicated in Figs. 1 and 3, the bracing-piece 30 being used to support the head. The drivingroll 11 is formed with suitable corrugatioi'is and may be built up, if desired, by rigidly securing a number of rings of the desired shape upon the spindle 6. The lower end of this spindle is supported in a suitable bearing in the base of the machine, and the stepped hearing 13 may be used, if desired. The wormwheel 12 is secured to this spindle and is engaged by the worm 14:, rigidly secured upon the shaft 16, which is mounted in suitable bearings 15 in the frame, as indicated in Fig. 6. The gear 17 on this shaft is engaged by the driving-pinion 18 of the electric motor or other driving means 19, so that in this way the driving-roll may be rotated at the speed desired. The sleeve 103 formed 'so as to loosely engage the driving-roll and serves to shroud the corrugations in this roll when the machine is used in flattening or spinning the corrugations formed in the cylinder. This sleeve is preferably constructed with a series or alining collars, as indicated, which are adapted to enter the corrugations of the cylinder 20 and secure the alinement of these corrugations as they are flattened. These alining collars may, however, be omitted and the flattening-roll have a plain cylindrical form.

The top of the spindle 6 operates in a bearing in the cap 4:, this cap being formed with the lug or projection 31, adapted to engage a suitable recess in the entablature to rigidly support the upper end of the spindle in operative position. This cap is formed with a sleeve which incloses the hydraulic cylinder 21, which works upon the piston 2 L, rigidly secured to the top of the head. The enlarged lower portion of this piston operates within the cylinder, the upper end of which is closed by the cylinder end 23, formed with stuiiing-boxes, as usual. In this way an annular water-space 9.8 is formed which communicates, through the opening 22 in the piston, with the inlet 29, so that when water or other fluid under hydraulic pressure is admitted to this inlet it 'llows into the cam-cylinder and raises the cap away from the spindle ol' the d riving-roll. The cap is formed with the guideroll 26, which engages the cam-groove 27 in the inside of the head, this groove being preferably given the curved contour indicatedin Fig. .10. In this way the head rises in a vertical direction until it is clear of the spindle (5, and thereafter it is given a partial rotation of the desired extent to swing it clear of the spindle and the cylinder on the driving-roll. Upon allowing the discharge of fluid from the hydraulic cylinder the cap descends by its own weight, or, if desired, positive means may be employed in some cases to assist its desired movement in which it swings into position over the spindle and thereafter descends upon it.

The traverse-roll 32 may have a built-up construction similar to the driving-roll 6 and may be formed by rigidly securing a series of rings to the spindle 7. This spindle is indicated as mounted in the boxes 36, which move in suitable guides in the frame and which may be traversed toward and from the driving-roll by suitable traverse-gear of any description. In Fig. 1 the traverse-bars 37 are indicated as pivoted to the boxes and are pivoted at their other ends to the blocks 106, which move in the guides 105 in the yoke 60. These blocks are also connected with the toggle-links 38 39, the links 39 being pivoted to move about the stationary blocks 61 in the yoke. The way bars 40 are pivoted to the toggle-links, as indicated, and their inner ends are pivoted to the distance-pieces 41, which swing about pins in the lugs 42 of the yoke. The links 43 connect these way-bars with the traverse-cylinder 44, mounted upon the differential piston 45 and operated as described in my Patent No. 737,277, granted August 25, 1903. A suitable stop 46 is preferably provided to limit the inward movement of the traverse-cylinder, this stop being operated by the screws 47,.having the worm-wheels 57 secured thereto. These worm-wheels are engaged by the worms 48 on the shaft 49 passing through the slot in the frame and which is connected by the bevelgears 50 51 with the shaft 52 of the air-engine or other motor 53, mounted on an extension 54 of the frame, indicated in Figs. 5 and 6. The bevel-gear 51 is splined to the shaft 52, so that it is allowed to move along this shaft and is held in engagement with the cooperating bevel-gear at all times. This stop and traverse mechanism operates, as described in my patent referred to, so that the traverseroll is actuated under hydraulic pressure through the toggle connections, which traverse the roll toward or from the driving-roll, the forward movement of this traverse-roll being positively limited by the stop, which may be adjusted from time to time to allow the desired extent of movement of the parts.

The yoke is supported at either end in suitable guides in the frame, and this yoke is engaged by the adjusting-screws 59, which cooperate with suitable nuts 62 in the yoke, the shanks of these screws passing through the sleeves 63 in the pillar 2 of the frame and having the worm-wheels 64 secured to them. Each of these worm-wheels is engaged and operated by a worm on the worm-shaft 66, which rotates in a suitable bearing 68 in the frame and is operated by the beveled gears 67 .69 from the shaft 70 of the electric motor or other driving device 71. By this means the mljusting-scrcws 59 may be rapidly rothe position of the yoke and its traverse mechanism and the connected traverse-roll, the end of the piston 45 passing through an aperture 104 in the pillar, as indicated.

The flattening-roll 8, which may be of such size as to be always in contact with and reinforced by the traverse-roll, is mounted in suitable bearings in the cranks 33, journaled about the spindle 7 of the traverseroll. These cranks are operated by the pistons 36, which move in the hydraulic cylinders 37, secured to the yoke, the rods 35 being connected by the links 34 with the cranks 33. 1n this manner the flattening-roll may be swung into the operative position shown in Figs. 1 and 4 or may be swung to one side, so that the yoke and traverse-roll may be bodily adjusted to the position indicated in Fig. 2 and the roll thereupon traversed into forcible engagement with the driving-roll, the parts assuming the position indicated in Fig. 2.

The spinning-boxes 111 and 121 are mount-- ed in suitable guides 109 and 135 in the frame, as indicated in Figs. 8 and 9, so as to slide therein, these boxes serving to support the ends of the spinning-shaft 116. The box 111 is indicated as engaged by the adjusting-screw 112, which may be rotated in any desired way and which serves to adjust the position of the box and the spinning-block secured thereto. A similar adjusting-screw 123 engages the lower box and adjusts the lower end of the spinning-shaft and box in a similar manner. The spinning-block 113 is eccentricallyimounted about the shaft 116 and is formed with the worm-Wheel 117, which is engaged by the worm 118, connected by the spline 130 with the shaft 119 in the bracket 120. As indicated in Fig. 4, this shaft is provided with the 0perating-wheel 131, and by rotating this wheel the worm-gear oscillates the spinning-block about the shaft 116. A number of sleeves 126 are mounted in the spinning-block, and every alternate sleeve, as is indicated in Fig. 9, is connected by the cranks 124 to the pins 129 in the operating-rod 114, so that the sleeves are rotated in unison by moving the rod. The other sleeves are provided with similar cranks 124, which are pivoted to the other operating-rod, 115. Each of these operatingrods is reciprocated by the hydraulic cylinder 127, secured thereto and provided with a suitable piston, which is connected with the lugs 128 on the block. A spinning-roll 125 is eccentrically mounted in each of the sleeves, the rolls being preferably provided with tapering shanks fitting within correspondingly-shaped bearings in the sleeves, the rolls being preferably held in position by suitable bolts 151, which may be used in connection with washers at their outer ends to allow the free rotation of the spinning-rolls. It will be seen by reference to Figs. 8 and 9 that by operating the rods and rotating the sleeves in which the spinningtated in unison and operate to quickly adjust I rolls are mounted the two rolls of each pair 3 may be made to approach each other and engage the opposite faces of the corrugated cylinder, as seen in Fig. 8. it, however, the sleeves are rotated in the opposite direction by the connecting mechanism described, the spinning-rolls will be moved out of engagement with these lateral faces of the corrugations and will engage and operate upon the opposite faces of the alternate corrugations of the cylinder. If desired, the spinning-block may be mounted so as to be vertically adjustable. This may be accomplished by forming the lower end of the shaft 116 with a suitable thread which is engaged by the threaded nut 154, which is rotatably mounted in the spinning-box 121. The worm-wheel 155, integral withthis nut, serves to rotate it as desired, and thus to vertically adjust the shaft 116, the upper end of this shaft passing loosely through a hole in the s )inning-box 111. The spinning-block 113 is secured to the shaft 116 by the inclosing sleeves 150 153, which are rig:

idly connected therewith, and the shaft and block are oscillated by the worm-wheel181 on the shaft, which is engaged and rotated by the worm 152.

Suitable adjusting-rolls, which may take the form indicated in Figs. 3 and 1, may be used to keep the corrugated cylinder 20 in proper position as it is rotated by the driving-roll. The guide-rolls are ad ustable in the frame and are guided so that they engage cylinders of varying size at substantially diametrical points, so that the cylinders are accurately guided in all cases during their rotation. These gulde-rolls 10 are mounted in suitable bearings in the blocks 99, these blocks being mounted in the guides 98, secured to the frame and being engaged by the adjusting-screws 97. As indicated, each of these adjusting-screws is provided with the beveled gear 96, secured thereto, and the coo iierating-gears 94 on the connecting-shafts 95 operate all these iuljusting-screws in uni.- son, the shafts 95, which are mounted in the bearings 93, being connected by the beveled gears 91 92 with the transverse operatingshaft 90, which may be rotated by the crank 107, (indicated in Figs. 3 and 4,) although it is of course understood that these guide-rolls may be adjusted in any other desired way.

A vertically-adjusted platform 7 at is mounted upon a series of rods 75, which are shown in Fig. 6 as engaged by the pinions 76 on the shafts 77, which run in the bearings 82. These shafts are provided with the beveled gears 78, meshing with the gears 79 on the shaft 80, which runs in the bearings 81, so that in this way by operating the hand-wheel 82 or other operating device all the racks on the rods are simultaneously operated and raise and lower the platform in a parallel manner. The movable table 73 is mounted in suitable slides on the platform and is operated by the links 89, shown in Fig. 3 as connected with the rock arms 88. These arms are connected to the shaft 87, shown in Fig. 1 as provided with the toothed segment 86, meshing with the rack 85 on the hydraulic cylinder 84:, which is operated to move the table as described in my patent referred to, the extent of motion of these parts being regulated by the hand-wheel In operating this machine a suitable cylindrical blank, preferably formed of welded sheet metal and heated to the desired extent, is slipped over the driving-roll and the traverse-roll moved up into engagement with the blank, which is rotated by the driving-roll. Corrugations of the arched form indicated in Fig. 2 may thus be formed in the cylinder 20. Thereupon the traverse-roll and yoke are Withdrawn and the cap t is raised and swung aside and the sleeve 103 dropped over the d riving-roll, so as to shroud the corrugations therein. The flatteningroll is then swung forward into the position indicated in Figs. 1 and 4:, and the traverse mechanism is thereupon operated so as to press the cylinder between the flattening-roll and the shrouded. rotating driving-roll, the arched corrugations being preferably flattened into the undercut crenelated form indicated in Fig. 1. Thereafter the spinning-head is oscillated from its inoperative position (indicated in Fig. 4) into engagement with the corrugated cylinder and the spinning-rolls are'forced into engagement with the lateral faces of the rotating cylinder, these rolls operating to burnish the corrugations and linish them in their undercut form. It is not necessary in all cases to withdraw the flattening-roll while the spinning operation is taking place, although this may be done in some cases. It is in all cases desirable, however, to maintain the guiding-rolls 10 in engagementwiththe cylinder, so as to secure its regular rotation of the cylinder, and for the same reason the table on which the cylinder is supported should be kept in proper vertical position at all times.

It is of course understood by those familiar with this art that many variations in the form, proportions, and numbers of parts of this machine may be made. Parts of the same may be employed without using the whole, and parts may be employed in connection with other devices Without departing from the spirit of this invention or losing the advantages of the same. I do not, therefore, desire to be limited to the details of the disclosure which has been made in this case; but what I. claim as new, and desire to secure by Letters Patent, is set forth in the appended claims.
